HCA-2200II ULTRA HIGH CURRENT AMPLIFIER. Our premiere amplifier created by legendary designer John Curl has been called by Stereophile,"...a benchmark product against which other amplifiers can be measured."

FEATURES

  • Two independent 1200vA toroid power transformers
  • Independent transformer windings for driver stage regulators
  • Higher driver rail voltages and independent regulation to prevent sag
  • 100,000uF computer-grade capacitors in power supply
  • Multiple polystyrene bypass capacitors in power supply
  • Cascode Class A input stages with matched J-FET pairs
  • Hand picked Mosfets in high voltage driver stages
  • 24 5OMhz, 15 ampere output transistors, B-matched complements
  • Output transistors direct-coupled without inductors
  • DC servo direct-coupled audio circuits with 0.3Hz rolloff
  • Linear tracking, instantaneous acting DC servos
  • Pure Class A operation up to >6 watts output; Class AB-1 thereafter
  • Balanced input circuits, XLR connectors, separately switched
  • Gold-plated metal structure RCA input jacks
  • Multiple temperature sensors and silver-cadmium relay protection
  • FR-4 glass epoxy circuit boards, outputs double clad for high current
  • Dual mono circuit topology for superior separation past 20kHz
  • Proprietary quick-settling bias circuits obviates warmup period
  • Silver plated audiophile-grade wiring drivers to outputs
  • Precision 1% tolerance Holco and Resista metal film resistors
